. l '5 claims; This invention relates to a window construction.

More particularly,l this invention relates to a window construction of the type which includes a plurality of window sections or panes each of which is adapted to be swung or pivoted about a horizontally extending axis into open and closed position and which window construction includes means for weather-stripping the window panes or sections when the latter are in closed position.

Window constructions of the type which include a plurality of window sections or panes which are adapted to be swung or pivoted about horizontally extending axes are well known and are particularly useful in such places as factories,

public buildings, oce buildings,` sun rooms and the like.

However, one diic'ulty which has been experienced with window constructions of this nature has been the diiilculty involved in weatherstripping the same and this has been due to the fact that the window sections or panes are movable and require clearance or space to enable them to be moved into and out of open and closed positions and this has, to a large extent, prevented them from being properly or adequately weather-stripped.

Accordingly, an object of the present invention is to overcome the foregoing and other objects which have been experienced in the use of the prior art window constructions of the character embodying a plurality of window sections or panes pivotally or hingedly movable about horizontally extending axes into and out of open and closed positions.

Another object of the present invention is to provide a window construction embodying a plurality of window panes or sections which are adapted to be swung about horizontally extending axes into and out of open and closed positions, and which window construction embodies novel means for effectively weather-stripping the window panes or sections when the latter are in closed position.

The new Window construction embodies a movable weather strip which is adapted to engage one side or vertically extending marginal edge portion of each of the window panes or sections, when the latter are in closed position, together with means for moving this weather-strip out of engagement with the said marginal edge portion of each of the window panes or sections.

Another object of the present invention is to construct the new window construction in such a manner that the means for moving `the window (Cl.v 21k-53) y panes or sections into and outof open and closed positions and the means for moving the weather-strip into and out of effective position are controlled bya common manually operable control member.

An additional object of the invention is to construct the same in such a manner that when the common manually operable control membcr for the window pane-moving means and the weather-strip-moving means is operated to eflll fect the window opening operation it first cooperates with said weather-strip-moving means to move the latter out of engagement withthe window panes or sections and subsequently cooperates with the window pane-moving means to 1U move the window panes into open position, whereas when the said manually operable control member is operated to effect the window closing operation it first cooperates with the window pane-moving means to move the window 20 panes into closed position and subsequently cooperates with the weather-strip-moving means to move the weather-strip into effective or weather-stripping engagement with the window panes.

Other objects will appear hereinafter.

The invention consistsin thenovel combination and arrangement of parts .to be hereinafter described and claimed.

The invention will be best understood by reference to the' accompanying drawings showing the r30 preferred form of construction and in which:

Fig. 5 is Aa. transverse or horizontal sectional View on line 5-5 in Fig. "3 showing the window panes in partially open position and showing the movable weather-strip moved out of engagement with the window panes; and

Fig. 6 is a fragmentary sectional view illustrating a modied form of one feature of the new window construction.

A preferred form of the new window construction is illustrated inFigs. 1 vto 5, inclusive, of the 55 drawings, is therein generally indicated at I8, and comprises a window frame I I which may be made in any suitable designs and in various materials such as wood, metal and the like, inasmuch as the particular design of the window frame is not essential to the present invention.

The particular form of the window frame II which is illustrated in Figs. l to 5, inclusive, of the drawings includes a pair of box-like housings I2 and I3 which form the sides or side walls of the frame, a top wall I4, and a bottom wall or sill I5.

The new Window construction includes one or more window sections or panes I6 which may be made of any suitable light-penetrable material such, for example, as glass, and each of which is mounted in a frame 22 which may be made of wood, metal or other suitable material. The window panes or sections I6 and` their frames 22 are adapted to be swung or pivoted about horizontally extending axes into and out of open and closed positions ina manner and by means which will be described presently.

Each of the movable window panes or sections I8 is pivotally or hingedly mounted-at one end upon a horizontally extending pintle or trunnion I8 (Fig. 5), and each of these pintles or trunions I8 is slidably mounted in an aperture or recess 45 which is formed in the wall 28 of the housing I3.

Each of the pintles or trunnions I8 also includes an inner end portion I8 which projects into and is rigidly secured in an aperture which is formed in the corresponding frame 22.

Each of the window pane sections or unitsl I8-22, etc., also includes a second pintel or trunnion 23 (Figs. 3 and 5) and each of these trunnions 23 includes an inner end portion 24 which projects into and is rigidly secured in an opening formed in the corresponding window frame 22. Each of the pintles or trunnions 23 also includes an outer end portion 25 which projects through and is rockably mounted in a movable weather-strip 28 (Figs. 4 and 5), which will be described presently, andeach of the trunnions 23 also includes a collar portion 59.

The weather-strip 26 is slidably mounted in an opening 21 which is formed in a vertically extending wall 28 of the box-like housing I2 of the window frame II. s

Provided in the box-like side wall I2 of the window frame II, between the inner and outer walls 28 and 28 thereof, is a vertically extending operating member or rod 38 which is slidably mounted in brackets 3I which are attached to the wall 28.

Provided on the lower end portion of the vertically extending operating member or rod 30 is a rack 35 and engaging with this rack 35 is a pinion 38. This pinion 38 is mounted on and carried by a horizontally extending and manually operable rod 31 which projects exteriorly of the window construction I8 through the bottom wall or sill I5 thereof and a handle 38 is provided on the rod 31 outwardly of the window and at the inner side thereof.

Carried by the vertically extending operating rod 38 is a series of vertically spaced projecting lugs 32 and each of these lugs 32 projects into and works in a cam slot 33 which is formed in a crank orl arm 34 and these cranks or arms 34 are mounted on the outer .end portions 25 of the trunnions 23 (Fig. 5).

Mounted in brackets 39 which are attached to the wall 28 is a group, consisting of at least two cam elements 48, for moving the weatherstrip 28 into and out of effective or weatherstripping position. Each of these cam elements 40 has a centrally disposed offset portion 4I and these oiset portions 4I engage with the Weatherstrip 26 on the outer side of the latter.

Each of the cam elements 48-4I has an arm 43 and the vertically extending operating rod 38 carries laterally extending lugs 44 each of which is engageable with one of the arms 43.

Attached to and carried by the weather-strip 28, on the outer side of the latter, are two brackets 53 each of which has an outwardly extending apertured portion 54 through which the offset central portion 4I of the corresponding cam element 48 extends. y

Provided in the inner wall 28 of the box-like side wall or housing I3 of the window frame I8 is a vertically extending groove 48 (Fig. 4) in which the vertically extending marginal edge portions 55 of the Window panes I6 are adapted to seat (Fig. 4) and provided in the weatherstrip 26', on the inner side thereof, is a vertically extending groove 41 in which the vertically extending marginal edge portions 56 of the window panes I8 are adapted to seat.

Provided on the vertically extending operating member or rod 38 are two spaced cams or bosses 51 each of which is engageable with one of the arms 43, for reasons to be explained presently.

The operation of the form of the new window construction which is illustrated in Figs. 1 to 5, inclusive, is as follows: When the window is closed the vertically extending marginal edge portions 55 and 56 of the window panes I8 are disposed or seated in the vertically extending grooves 48 and 41 which are formed in the wall 28 and in the weather-strip 28, respectively (Fig. 4), and hence the new window is thus sealed or weather-stripped when in closed position.

Accordingly, in order to open the new. window it is merely necessary to grasp the handle or knob 38 and turn or rotate the same and the shaft 51 (clockwise, Fig. 1). 'I'his movement of the handle 38 and its supporting shaft 31 acts, through the pinion 36 and the rack 35, to raise the vertically extending operating member or rod 38.

As the operating member or rod 38 is raised, the cams or bosses 51 carried thereby engage the arms 43 and rock the cam elements 48 in a direction to move their offset center portions 4I (left to right, Fig. 4) in the apertured portions 54 of the brackets 53, thus moving the weatherstrip 26 (left to right, Fig. 4) and thereby moving the grooved portion 41 thereof out of engagement with the marginal edge portion 58 of the window panes I8.

As the weather-strip 28 is thus moved out of engagement with the marginal edge portions 56 of the window panes I6 the weather-strip 28 engages the collar portions 58 of the trunnions 23 as the weather-strip continues to move (left to right, Fig. 4) it thus moves or carries with it the window panes I6 and their frames 22 until the edge portions 55 of the window panes I6 are moved out of engagement with the groove 48 in the Wall 28.

Thereupon, and as the operating member or rod 38 is thus raised, the lugs 32 carried thereby travel up the cam slots 33 in the cranks 34 and in so doing pivot the window panes I6 and their frames 22 into open position, as in Fig. 1.

However, when it is desired to close the window this may be accomplished by turning the handle 38 and its supporting shaft 31 in the opposite direction (counterclockwise, `Fig. 1), this motion df the handle sa and its supporting shaft 31 acting, through the pinion 36 and rack l5, to slide the vertically extending operating member or rod 30 downwardly.

As the operating rod 30 is thus lowered the lugs 42 carried thereby again travel down the cam slots 33 in the cranks 34 and in so doing swing the window panes I6 and their frames 22 back into closed position.

Likewise, as the operating member or rod 30 is thus lowered, and after the window panes I5 have been closed in the manner described above, the lugs or pins 44, which are carried by the rod 30, engage the offset or cam portionsl of the cams 4U and in so doing rock the offset vportions 4| thereof back into engagement with `the weatherstrip 26. This slides the weatherstrip 26 back into the closed or effective weather-v stripping position in which it is shown in Fig. 4` and in which .position the marginal edge portion 56 of the window panes I6 againrest in the groove 41 which is formed in the weather-strip As the weather-strip 26 is thus'moved back into effective or weather-stripping' position,y it

engages the window panes I6 and. their .frames 22 and in so doing slides the said window panes I6 on their pivots or trunnions I8 and 23 back into their normal and closed position, as in Fig.-

4, and in which position thevmarginal edge portions 55 of the window panes I6' againenter .the groove` I6, Vthus completing the. weatherstripping of the window.

A suitable stop or retaining member 58 (Fig. 5) may be mounted in the box-like side wall .|2, and on the wall 28, in association with each of the pivots or trunnions 23, and so as vto .retain the said pivots or trunnions against outward displacement from theirv position of use (left tovright, Fig. 5).

A slightly modified form of the invention is illustrated in Fig. 6, and in this form of con-- `struction parts which correspond to similar parts in the form ofconstruction which is illustrated in Figs. l to 5, inclusive, are 4given the same reference numerals followed by the letter ffa.

The modied form of construction whichv is intimated in Fig. 6 is substantially simnar to.

the form of construction which is illustratedin Figs. l to 5, inclusive, except for the. c onstruction of the weather-strip 49 and the trunnions or pivots upon which the Window Apanes are mounted, and the retaining device or stop associated therewith. l g

` Thusit will be noted that vthe weather-strip 45 diners from the weather-strip 26'in' that it is provided on its inner surface with recesses 50- ferred forms of construction 'for carrying my invention into eiect, these are capable of variation and modification, without departing from the spirit of the invention. I,l therefore, do not wish to be limited to the precise detailsof con--v vstruction set forth, but desire to `availmyself of such variations and modifications as come within the scope of the appended claims.-
